Electrical discharge at the voltage 440 V near the surface of the ferrite piece is used for initiating of electronic energy explosion (EEE) in the air. In the active zone of EEE proceeds the nitrogen oxidation branched chain reaction. The mirrors of an optical resonator are positioned at both sides of the active zone of EEE. Blue super-luminescence is observed at these conditions. Addition of moistened sodium nitrate powder in the active zone of EEE results in appearance of laser generation in red and green regions of spectra. The obtained results are interpreted in terms of branched chain reaction producing electronically excited atoms O(1S) and molecules NO(B 2ÐÂ) and NO2*.
